What are the key tasks involved in managing application security in Pega?

Managing application security in Pega involves critical activities that ensure the protection of data and the integrity of the application. The defining of access groups, roles, and privileges is fundamental in establishing who can access specific data and perform particular actions within the application. By organizing users into access groups and assigning them distinct roles, you create a structured approach to permissions that aligns with the security requirements of the organization.

In addition to setting up roles and groups, encrypting data is also a vital component of application security. This encryption safeguards sensitive information from unauthorized access and breaches, reinforcing the security framework of the application.

On the other hand, while designing user interfaces, developing application workflows, and creating multi-language support are all important aspects of application development, they do not directly pertain to security management tasks. They focus more on usability, functionality, and accessibility of the application rather than protecting it from vulnerabilities or controlling user access. Thus, the comprehensive approach to managing application security is embodied in the activities related to access controls and data encryption, making this option the correct choice.
